1 Form+Function NEWS & INFORMATION FROM HAMILTON FORM SPRING 2012 Project Spotlight San Francisco 49ers Stadium Clark Pacific C lark Pacific was successful in winning the contract worth $15-$20 million to produce over 2,000 precast pieces for the new San Francisco 49ers stadium. Casting began in April and will be completed early in Hamilton Form and Clark Pacific worked closely together to develop a practical and efficient formwork package for the project. Matt Engleking, the project manager at Clark Pacific notes, From the big picture to the smallest detail, the team at Hamilton Form worked with us to help ensure we produce a quality product for the long standing rivals of America s Team. Some forms were built with magnetic, instead of bolt down rails, to make change overs more efficient. The forms arrived at Clark Pacific ahead of schedule and ready for set-up. The high quality forms fit together perfectly and were easy to set-up and install in our production plant. Our castings look great and we look forward to completing another successful project with formwork designed and fabricated by Hamilton Form, beamed Matt. (continued inside) Hamilton Form delivered 260 bed feet of triple and double seating risers for the project. Forms for higher volume products were made in longer lengths so that several products could be cast simultaneously. Several sections of tub forms were also delivered. Some will cast both single and double walkways in the same form. Forms for low quantity pieces were configured to accept risers to extend the top of the upper stem so that additional products could be cast in the same form.

2 Project Spotlight San Francisco 49ers stadium (Continued) T The new 49ers stadium is scheduled to open in he $1.2 billion stadium for the San Francisco 49ers will be located in Santa Clara, California about 35 miles south of San Francisco. It will seat 68,500 and have 165 luxury suites and 9,000 premium club seats. Two thirds of the seats are located in the lower bowl, making it one of the largest lower bowls in the NFL. The seating capacity can be expanded to 75,000 for special events and will include over 100,000 square feet of flexible meeting space to further expand its multi-use facility capability. The stadium is registered with the USGBC under its LEED program. Sustainability features include a green roof, solar panels and will use recycled water for landscape, toilets and urinals. The building and walkways will be made with high solar reflectance materials that contain a large percentage of recycled material. The stadium is expected to open for the 2014 NFL football season. Candlestick Park While the new stadium is exciting, it s interesting to note some of the history of the 49ers old stadium. Candlestick Park was originally built in 1960 for the San Francisco Giants. It was the first modern baseball stadium built entirely of reinforced concrete. Because of its location on the bay, it was reputed to be the coldest and windiest stadium in the country. It was designed for radiant heat in the dugouts, but pipes were placed outside, instead of inside the concrete, so the system never really worked. The Beatles played their last live concert there in August In 1971 the 49ers moved in and shared the stadium with the Giants until In October of 1989, just before Game 3 of the World Series, the Lomo Prieta earthquake struck San Francisco. Because of game-related sports coverage, it was the first major earthquake in the United States to have its initial jolt broadcast live on television. The game was cancelled for nine days while the aftermath of the earthquake that killed 63, injured 3,757 and caused $6 billion in damage was dealt with. Candlestick Park, however, sustained only minor damage. Today, Candlestick Park is the oldest un-renovated stadium in the NFL and is destined to be vacated by the 49ers in Attention All Epicureans Call for Recipes The 2012 Handy Epicurean Cookbook is now in production.

3 Formwork Dual Battery Molds make Light Work for Sound Wall Production Speed Fab-Crete, Fort Worth, Texas A number of bridge and highway construction projects across the country have been keeping many precasters busy. One product often used on highways is sound walls. Speed Fab-Crete was recently awarded a contract to supply 170,000 square feet of sound wall panels in varying lengths and heights for an interstate highway in Texas. To produce the wall panels, two dual battery molds were built. Each mold casts the walls with an integral column on one side. The two forms differ in that one is designed with the column at the top of the mold so that panels are cast on-edge, while the other mold is configured to cast the product in the asinstalled position. The dual battery mold that casts product on-edge is 42 long with nominal 13 high sideforms and 4 soffit. The column is formed by a block-out at the top of the mold, to allow for production of products up to 21 tall in a 13 high form. The mold has bolt-on headers on each end and internal headers so that four products can be cast at the same time. Dual battery mold built and assembled at Hamilton Form. The second mold sets up similar to the first but casts the product in the as-installed position with an integral column at the end of the mold. This mold will cast products that are 13 high and up to 21 long. Product lengths can be adjusted with internal headers. Interior sideforms are fixed in place on a sleeper system. The outer sideforms are split into two 21 sections that roll back on wheel carriages and tracks. A catwalk runs between the two interior sideforms for access to the top of the mold. Both under ties and top ties were supplied. The top ties are welded into a single assembly for each panel cavity for quick installation and removal. Speed Fab-Crete will be installing form liners for a decorative finish on the face of the panels. A catwalk provide access to the top of the mold. Column formed at end. Each sideform is 13 high. Hangers are used to cast the column at the top.

4 Equipment Spotlight STRESSING? We ve got you covered. Hydraulic Power Unit Pull-Type Tensioning Jack The Hydraulic Power Unit is designed for precision performance and ease of use. Its large gauges are easy to read and a pivoting cover protects the gauges when not in use. It s easy to calibrate and can pull 0.6 strand at 8 seconds per foot. It can be mounted on forklift tubes or cart. Rugged and durable, single strand Pull Type Tensioning Jacks have an anti-twist bar on the pulling yoke which can be used to measure elongation. It comes with a magnetic torpedo to make sure the jack is level and a Y-sling chain for easy manipulation. Available in 24, 36, 48 and 60 strokes for ½ or 0.6 strands. Center Hole Ram Tensioning Jack Lighter and easier to handle, the Center Hole Ram is typically used on shorter beds, especially when space at the end of the bed is limited. Available in 12, 20 and 24 strokes for up to ½ strand. Positioning Hoist and Frame Strand Hold-Ups Strand Needles Depressor Beams For girder production, Strand Hold Ups keep strand properly aligned when producing beams with draped strand. The base plate sits on top of the soffit. The vertical plate has a series of holes fitted with strand rollers. Different vertical plates can be used with the same base plate for use on multiple beds. Pre-feed strand through your headers before dropping them into place with Strand Needles. These steel rods with a receiver at one end make a cumbersome task almost effortless, saving time and money. Made for ½ or 0.6 strand in 6 or 9 lengths. Hamilton Form has both Top and Bottom Depressor Systems for depressing strand in double tee beds.

Did you know that the Eiffel Tower in Paris is actually six or seven inches taller in the summer than it is in the winter? That s because the 1,050 foot tower expands when it s hot and contracts when it s cold. Now that summer is here, remember this same phenomenon applies to steel beds. And, it s one of the reasons one should always allow for movement when installing long-line steel beds.

5 Formwork A new twist on a stepped form S tubbes Precast in Ontario, Canada came to Hamilton Form with a request to build an unusual form. The products are conical with a relief panel on the face. The back of the product is stepped. After reviewing product drawings, Hamilton Form s engineers designed an overall form approximately 6 high x 10 long with a curved base to create the conical pieces. The form is shaped to produce products that change from 4-10 at the bottom to 7-7 wide at the top. A raised insert shapes the relief panel on the face of the product. A one-piece corded back pan fits over the base. It attaches to headers and an end rail and is held in place by top ties. Concrete is poured from the top of the form. The headers, end rail and back pan are pulled away from the base for stripping. Base form Corded back pan Front of product with relief panel Stepped interior
